As a physician and as a pilot, I think it lets me be a pretty good translator having one foot in the medical world and one foot in the flying world. Sometimes when the medical guys come in and speak medical stuff to the pilots, the pilots really don't know what they're saying.

The views of the Earth are really beautiful. If you've ever seen a space IMAX movie, that's really what it looks like. I wish I'd had more time just to sit and look out the window with a map, but our science program kept us very busy in the lab most of the time.

I was interested in flying beginning at age 7, when a close family friend took me in his little airplane. And I remember looking at the wheel of the airplane as we rolled down the runway, because I wanted to remember the exact moment that I first went flying... the other thing growing up is that I was always interested in science.

As much as we've enjoyed it up here, we're also starting to look forward to seeing all the people back on Earth that we miss and love so much.

Although as a boy I had dreamed about going into space, I had completely forgotten about that until one day I received a call from an astronaut, who suggested that I should join the program.

The great thing about being an astronaut is you kind of get to do a little bit of everything. I mean, we're going to ride a rocket uphill.
